Why does my child’s skin suddenly turn dark?

Children's skin is relatively tender, and there are many reasons that may cause it to suddenly turn dark. The most direct and obvious one is in the summer, when prolonged exposure to the sun can cause children's skin to become sunburned and dark. Sometimes some diseases can also cause the skin to suddenly turn dark, which should be taken seriously. Let’s take a look at some common reasons why children’s skin suddenly turns darker.

1. The natural environment damages the skin.

The culprit is ultraviolet rays, which stimulate the melanin in the skin and induce skin lesions such as freckles. Even on cloudy days, the "ultraviolet rays" are still strong. Ultraviolet rays can cause skin darkening, aging, and wrinkles. Human skin's response to ultraviolet rays causes redness, tanning and increased thickness of the skin's epidermis in acute reactions, and leads to skin aging in chronic reactions. In the summer, if you still want to have fair and flawless skin, you should do a good job of sun protection, especially when the UV index reaches 7 or above, it is more likely to damage the skin. You should strengthen sun protection and don't be afraid of trouble and cause regret in the future. In fact, humid air, sunlight coming through car windows, and even indoor light bulbs and computers are all the culprits that cause your skin to become darker.

2. Certain diseases are triggers.

Many diseases can change the normal skin color and make it darker. The most common ones include endocrine system diseases, chronic wasting diseases, malnutrition diseases, etc. These diseases can cause the skin to turn brown or dark brown, which is particularly obvious in exposed areas such as the face, back of the hands, joints, or areas that are under pressure and friction. For example, chronic liver disease can cause chloasma on the face or darkening of the area around the eye sockets. In addition, the melanin of melanosis patients is mostly accumulated on the face, especially on the forehead, cheeks, behind the ears and neck, which is very obvious. Another type of disease is skin diseases, especially skin diseases caused by allergies to certain foods, such as raw onions, raw garlic, peppers, peppers, leeks, wine, fish, shrimp, kelp, chicken, duck, pig's trotters, pig's head and other foods, which can also induce skin allergies, resulting in rashes and finally leaving pigments to make the skin darker.

3. The foods you like are rich in zinc, copper and iron.

Certain foods are also the cause of darkening of the skin. Foods rich in metal elements such as copper, iron, and zinc have this disadvantage. These metal elements can directly or indirectly increase the amount and activity of substances such as tyrosine and tyrosinase that are related to melanin production. These foods mainly include animal liver, kidney, oysters, shrimp, crab, beans, walnuts, black sesame, raisins, etc.

Therefore, when you suddenly find that your child's skin has become darker, it is best to take the child to a dermatologist for examination to rule out the cause of the disease. You can also eat more foods that can effectively prevent the skin from darkening, try to reduce the time of direct exposure to ultraviolet rays, and adjust the diet structure and supplement some nutrients appropriately.
